How to choose the size of traditional slingshot?

The size is related to the habits of users and everyone.

Many novices are puzzled about the size of traditional slingshots. Some old birds are not very clear about this. Even if they bought n bows, they felt smaller and smaller. In fact, the truth is that they didn't choose the right slingshot from the beginning. Choose a slingshot that suits you, just like a pair of shoes that suit you. Running a marathon with a size 42 foot and a pair of size 45 shoes is definitely not comfortable.

First of all, let's talk about what the width of the hand determines the height of the bow: that is to say, the width of the index finger root and the little finger root plus the bow arm x3 (the diameter of the upper bow eye+the lower bow eye+the bow arm at the tail) plus the size of the bow eye is the maximum height of your slingshot, and 2mm is also acceptable.

Hand-length fixed arched door: the size from the root of thumb to the tip of index finger is divided by 2, and the width of arched door is subtracted from the diameter of two arched arms, which can be as small as 2mm, and the arched door with large diameter is smaller.

Specify the arch surface: the dimension from the first joint of the index finger to the root is basically the length of the arch surface.

Nameless designated bow and waist: the size of the bow after wrapping, MINUS the diameter of the first joint of the ring finger to the two bow arms at the root, is basically the width of the bow and waist. Considering that the bow is wrapped, minus 2mm, the first joint of middle finger and ring finger just buckles the bow and waist, and the relative strength is also the greatest, because the correct bow is pulled forward with the bow tail. If these two fingers are not driven by the little finger tied to the bow, it will be very difficult, and it is easy to grow cocoons after hitting the little finger.

After these basic dimensions are determined, it depends on the craftsman's craft, perfect corner and slope, consistent symmetry and flatness.
